Polarized light are those that are vibrating in one direction- in a single plane such as up and down. Those that are vibrating in more than one direction -- in more than one plane such as both up/down and left/right -- are called unpolarized light. Generally‚ unpolarized light can be considered to be vibrating in a vertical and a horizontal plane. To polarize light‚ one can transmit the light through a polariod filter which will only allow light of single polarity to pass. The resulting light will be

properties of electromagnetic waves and interactions that make Doppler radar possible. (13 points) A Doppler radar is an important tool used to measure the velocity and direction of a moving object. The Radar actually has transmitters that produce and release electromagnetic waves in the form of microwaves or radio waves. These waves are sent out and when they reach something they reflect or bounce back to the source or transmitter. It is noticed that when the waves are reflected back they are

What are UltraSonic Waves? Ultrasonic waves are sound waves with frequencies high about human hearing and short wave lengths. Sound waves have frequencies about 20‚000 to 100‚000. Also Ultrasound frequencies range from 20 kHz (the upper range of hearing for a young adult human) through 150 kHz (audible to some bats and other creatures)‚ right up to 10 MHz (used in some medical treatments and industrial cleaning applications). While these frequencies overlap with those of radio waves‚ they are different

Longitudinal and transverse waves Sound is transmitted through gases‚ plasma‚ and liquids as longitudinal waves‚ also called compression waves. Through solids‚ however‚ it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure‚ causing local regions of compression and rarefaction‚ while transverse waves are waves of alternating shear stress at right angle to the direction of propagation

Objective The objective of this lab was to use standing waves in a resonance tube in order to measure the speed of sound. Standing waves were used due their constructive and destructive interference‚ which lead to nodes and antinodes in the wave.The nodes could be marked because they were silent‚ and the antinodes were loud. Hypothesis We expect to find a linear relationship between wavelength and period because the speed of sound is constant. The frequency will inversely change the wavelength

F 1 Somer F English- Mr. Recchio Hour 2 Summer Reading Essay The novel “The Sound and the Fury” by William Faulkner tells the story of the Compson family’s downfall after the civil war. The story takes place in 1910 and 1928 in Mississippi‚ and centers on the Compson family’s three sons: Benjy‚ Quentin‚ and Jason‚ as well as their unconventional obsessions with their sister Caddy. To understand the sons’ obsessions‚ one must understand that the Compsons are an extremely dysfunctional family

Stoneley-wave attenuation and velocity are sensitive to fracture and formation permeability‚ especially at low frequencies. Stoneley-wave velocity declines‚ and its attenuation increments‚ as permeability increments. Beginning endeavors (started in the 1970s) to get permeability information from Stoneley information was unsuccessful because neither the significant low-frequency instruments nor the proper handling techniques had been created. The parallel advancement of present day multi-pole array

Although the number of waves per larva was different‚ it was higher than the waves produced in Table 2‚ the ChR2+ group. Larvae from this plate contracted immediately when the light was turned on and only produced waves during the interval the light was not on. Because the light flashed a set amount of times per second‚ the larva was not able to complete a full wave. This became more evident as the light continued to flash in a shorter time interval as the number of waves decreased as the MRR increased
